Answer:
C
Step-by-step explanation:
Given
x² = 36 ( take the square root of both sides )
[tex]\sqrt{x^2}[/tex] = ± [tex]\sqrt{36}[/tex]
x = ± 6
that is x = - 6, 6 → C
Answer: x=6
Step-by-step explanation: To solve for x you do the opposite operation to both sides so since x is squared you'd find the square root of x^2 which would be x and the square root of 36 which is 6.
